A vehicle suspension comprises a frame, a front axle and a rear axle and two L-shaped levers mounted on the frame. The axles are rigid or have independent suspension, or one is rigid and one has independent suspension. Each axle is attached movably to the frame by means of a bearing unit and two reactive tie rods. One end of each of the L-shaped levers is kinematically connected to the corresponding axle while the other ends are interconnected by a connecting tie rod. An increase in the stability of the suspension is achieved.

A utility vehicle includes a plurality of ground-engaging members, a frame, a powertrain assembly, a front suspension assembly, and a rear suspension assembly. A cargo bed may be supported by the frame at the rear of the vehicle. The vehicle also includes an operator seat and at least one passenger seat positioned within an operator area. In one embodiment, the vehicle includes doors to enclose the operator area.

Various embodiments provide a suspension structure and a vehicle, and relates to the field of vehicle technologies. In some embodiments, the suspension structure includes a leaf spring assembly, an upper arm, a steering knuckle, and a shock absorber. The leaf spring assembly includes two leaf spring constructions arranged in a front-to-rear direction. Both leaf spring constructions are arranged transversely relative to a body structure, and the middle part of each leaf spring construction is fixedly connected to the body structure; and each of the leaf spring constructions is provided with two free ends in a length direction, and each of the free ends is provided with a first mounting portion and a second mounting portion. One end of the upper arm is rotatably connected to the body structure.

A suspension apparatus for a vehicle including a drive unit configured to provide driving power to a wheel, a first knuckle coupled to the drive unit and configured to transmit a steering force to the wheel, a second knuckle disposed to face the first knuckle and configured to support the first knuckle so that the first knuckle is rotatable, a suspension arm extending from a vehicle body and configured to absorb impact applied to the wheel, a bushing unit provided between the second knuckle and the suspension arm and configured to support the second knuckle so that the second knuckle is rotatable relative to the suspension arm and a rotation restriction unit provided on the bushing unit and configured to selectively restrict a rotation direction of the second knuckle.

A utility vehicle includes a plurality of ground-engaging members, a frame, a powertrain assembly, a front suspension assembly, and a rear suspension assembly.

In one embodiment, the vehicle includes doors to enclose the operator area.

A low suspension arm strut coupling is provided for a suspension of an off-road vehicle. The suspension comprises a lower suspension arm that is hingedly coupled between a chassis of the off-road vehicle and a spindle assembly that is coupled with a front wheel. An upper suspension arm is hingedly coupled between the chassis and the spindle assembly. A strut is coupled between the lower suspension arm and the chassis. A lower pivot couples the strut to the lower suspension, and an upper pivot couples the strut to the chassis. The upper and lower pivots provide a lower center of gravity of the off-road vehicle and a relatively smaller shock angle. The lower suspension arm is reinforced to withstand forces due to movement of the front wheel and operation of the strut in response to travel over terrain.

A universal axle-hub assembly is provided for an off-road vehicle. The universal axle-hub assembly comprises a wheel hub that receives a constant velocity (CV) axle snout into an opening extending through an axle support of the wheel hub. An outboard-most portion of the opening is a splined portion that engages with similar splines disposed on an outboard-most portion of the CV axle snout. An inboard-most portion of the opening is a smooth portion that receives a smooth portion of the CV axle snout. The axle support extends through an entirety of the width of a bearing that supports the wheel hub, such that the bearing supports the smooth portion of the CV axle snout and substantially eliminates shear forces acting on the splined portion of the CV axle snout. A bearing carrier supports the bearing and may be fastened onto a trailing arm or a spindle of the off-road vehicle.

A suspension system including a Chebyshev-Lambda (CL) mechanism, at least one linear motion mechanism and a spring-damper assembly, the CL mechanism including a suspension-arm, a support-arm and a first rotating-arm, an end of the rotating-arm being configured to be coupled with a reference frame at an anchoring-node, an operational-end of the suspension-arm being configured to be coupled with a suspended-mount at a first node, an end of the support-arm being configured to be coupled with the reference frame at a support-anchoring-node, the linear motion mechanism configured to be coupled with the reference frame via at least one anchoring node, an end of the linear motion mechanism being configured to be coupled with the suspended-mount at a second node, and the spring-damper assembly including at least one spring and at least one damper, wherein respective first and second ends of the spring and the damper are coupled between two points.

A damper assembly includes an outer cylinder, an inner cylinder positioned at least partially within the outer cylinder, a cap coupled to the inner cylinder, and a plunger positioned radially inward from the inner cylinder and coupled to a rod. The plunger, the cap, and an interior of the inner cylinder at least partially define a first chamber. The suspension system further includes a passage extending through the rod and fluidly coupled with the first chamber, a piston coupled to the inner cylinder and extending radially outward toward the outer cylinder, a first port in fluid communication with the plunger through the passage, and a second port in fluid communication with the piston. The piston, an exterior surface of the inner cylinder, and the outer cylinder at least partially define a second chamber.

A driverless transport system comprising a chassis (1), drive wheels (2) and jockey wheels (3), wherein, on each of a first side of the chassis (1) and a second side of the chassis (1) opposite the first side, a floating axle (4) arranged in the longitudinal direction is pivotably connected to the chassis (1) at a connection point (5) assigned in each case, a drive wheel (2) being arranged at one end of each of the floating axles (4) and a jockey wheel (3) being arranged at the opposite end of each of the floating axles (4), the driverless transport system additionally having a floating axle (6) arranged in the transverse direction which is aligned transversely to the two floating axles (4) arranged in the longitudinal direction and is pivotably or fixedly connected to the chassis (1) at an assigned connection point (5), a jockey wheel (3) being arranged at each end of the floating axle (6) arranged in the transverse direction.
